To CLZZ whom it may, concern.-

Be it known that I, MORGAN D. KALBAOH, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have made certain new and useful Improvements in Rotary Engines, of which the following is a specification.

My invention is an improvement in rotary engines; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a longitudinal section of my engine on about line 1 1 of Fig. 2. Fig. l is a detail perspective view of the feed-tube and the reversingvalve thereon. Fig. 2 is a cross-section on about line 2 2 of Fig. 2. Fig. 3 is a detail perspective view of the body portion of the valve-head. Fig. at is a detail perspective view illustrating one of the cut-off valves and the devices for operating the same. Fig. 5 is a detail perspective view of a fragment of the casing, partly in section, showing the guides for the blades. Fig. 6 is a detail perspective view of one of the blades. Fig. 7 is a detail perspective view of one of the spring-actuated rods interposed between the blades and the yokes. Fig. Sis a detail perspective view of one of the yokes, and Fig. 9 is a detail perspective view of one of the levers which connect the adjacent yokes.

In carrying out my invention I employ a casing which in operation revolves around the valve-head and is composed of the outer cylinder A, the inner cylinder A, and the radial plates A which connect the inner and outer cylinders and form guides for the blades B, which operate radially in the said casing and are movable into and out of the interior or bore of theinner cylinder A, as will be understood from Fig. 2 of the drawings. The cas ing also has ends or heads ctand a, the latter being suitably secured to the shaft 0, which may be supplied with a pulley or other means for transmitting the motion of the casing, which latter revolves around the valve-head The head 00 turns upon the projecting tubular stem D of the valve-head D, presently described.

The blades B, of which I employ three equidistant from each other, operate between the adjacent connecting-plates A and move inward and outward by the operation of the le ver devices and the bearing of the inner edges of the said blades upon the surface of the valve-head. The partitions or connectingplates A are provided between their ends with the recesses A in which operate the ends of the yokes E, as shown in Fig. 2. These yokes are provided at their ends with the laterally-projecting pins or studs E for engagement with the lever F and have in their under sides, between their ends, the groove or seat E which receives the central rounded portion G of the pin G. The pin G is provided at its ends with the square portions G which operate in the grooves B in the outer edge of the blade B, at the opposite sides of the latter, such blade being provided in its outer side with a central recess B within which operates the central portion of the yoke E in certain positions of the parts. The springs G bear between the non-circular ends G of the pins G and their respective blades and operate to press such blades normally toward and against the valve-head D and at the same time permit a yielding joint between the said plates and their respective yokes. The levers F pivot between their ends at F to the outer ends of rocking whose inner ends are pivoted at f to the inner cylinder A, and the opposite ends of the levers F are slotted at f to receive the ends of the yokes E, and the arms F formed by said slots f, are slotted at f to receive the pins E of the yokes, so the levers and yokes may operate as desired and may have a sliding movement along each other at their meeting ends, as will be understood from Figs. 2, S, and 9. By the described construction it will be noticed the movement of the bladesB are related to each other, and the movements of one will effect a proper relative movement of the others, so that each blade controls the others and is in turn controlled thereby.

The valve-head D is approximately oval in cross-section, with its major axis of a length approximately equal to the inner diameter of the inner cylinder A, and is provided at its ends with what for convenience of reference I term the abutments I-I,which bear snugly within the inner cylinder and form abutments for the steam, which operates between them and the blades in the operation of the engine. This valve-head has a body portion bars F (shown in detail in Fig. 3) preferably composed of the central section d and the end sections d, suitably secured to the central section, this construction being preferred for convenience in manufacturing the head and in producing the chambers and ports therein, as will be presently described. I also preferably provide the portions d with grooves d to receive suitable packing-strips, as will be understood from Fig. 2 of the drawings. The valve-head D has the integral tubular stem D and is provided at the inner end of the bore of said stem with a chamber I for the reversing-valve J. This chamber I is circular in cross-section, so the reversing-valve can be turned therein, and steam-passages K and K lead from the valve-chamber I outwardly and open on oppsite sides of the abutments H, such steam-passages being provided at L with seats for the cut-off valves M and M, which operate, respectively, in the steam-passages K and K, as will be understood from Fig. 2 of the drawings.

The cut-off valves are pivoted at m, so they can lock to the different positions shown in Fig. 2, and they are connected by links N with the swinging ends 0 of levers O, which levers are arranged in pairs and are pivoted at their adjacent ends 0 to the body-section cZof the valve-head. Thevalve-head is grooved at d to receive the levers O, as shownin Fig. 3.

The reversing-valve J is flattened on opposite sides at J to discharge the exhaust, and said valve is on the inner end of the tubular feed-pipe J the bore .F having discharge-ports J which may be adjusted into register with the steam-passages K or K, as shown in Fig. 2. The exhaust passes from the passages K or K along the flat sides J of the reversing-valve and thence into the tubular stem D of the valve-head and out through a discharge-pipe P, as shown in Fig. 1. Means are provided for shifting the position of the reversing-valve, consisting, as shown, of a lever Q on the feed-shaft J and having an arm Q, grooved at Q to slide along the sector Q mounted on the stem D, as will be understood from Fig. 1 of the drawings.

Suitable stuffing-boxes and packing-strips may be provided wherever necessary.

In operation when the parts are in the position shown in Fig. 2 the steam will be delivered from the reversingvalve to the steampassages K and the steam-passages K will be opened to the exhaust-ports provided along the flat sides of the reversing-valve. The blade B at the upper right-hand side of Fig. 2 will bear upon its lever O and will open the cut-off valve which controls the upper passage K, so the live steam will be supplied to operate between the upper abutment and the said blade B and cause the casing to turn in the direction indicated by the arrow in Fig. 2. The lower cut-0E valve M will be opened and permit the discharge of the exhaust from in front of the blade B at the lower right-hand side of Fig. 2, while the blade at the left in Fig. 2 will have completed its operating stroke and will have adjusted to such position as to permit the lower cut-off valve 1 to close, the steam then operating expansively between the lower abutment and the blade at the left in Fig. 2 until the blade at the lower right-hand side of Fig. 2 reaches a point where it will operate. upon the lever of the lower cut-0E valve M and open said valve to permit the passage of live steam as desired. To reverse the engine, it is only necessary to turn the reversing-valve from the position shown in Fig. 2 to a position where its ports J will register with the steampassages K, when the live steam will pass out through the passages K and the exhaust will pass through the passages K.

By my invention I provide an engine whose direction is readily controlled and in which the blades will so control the cut-off valve as to secure'advantage of the direct action and the expansion of the steam in a simple and effective manner.

It will be understood that, as best shown in Fig. 1, the tube of the valve-head is clamped fast to avoid revolving in the opposite direction from that of the outer casing or cylinder, to which end the tube may be clamped in the bearing shown at the right in Fig. 1.
